replace process exit with more detailed exit in src/bootstrap/*.rs

[kons-9]

Fixes#98830

I implemeted "detail_exit.rs" in lib.rs, and replace all of std::process::exit.
So, error code should panic in test code.

// lib.rs
pub fn detail_exit(code: i32) -> ! {
// Successful exit
if code == 0 {
std::process::exit(0);
}
if cfg!(test) {
panic!("status code: {}", code);
} else {
std::panic::resume_unwind(Box::new(code));
}
}

Thanks, this is great! After you address the comments, can you squash the commits? There are instructions at https://rustc-dev-guide.rust-lang.org/git.html#advanced-rebasing.

[jyn514]

@kons-9 I see you added a new "squash the commits" commit but that didn't actually squash them. After squashing you should have exactly one commit in the PR. Make sure you use git push --force instead of merging.

[kons-9]

Sorry for the mishandling of the operation. I think this is probably done.
